A Classy Affair in the Country by Margaret Amatt

It’s hate at first sight… But he’s about to dismantle her walls brick by brick
Young heiress Ophelia Chattan-Blythe needs a miracle to save the family estate, and working with Brann Duthie – the ruggedly handsome, popular, and extremely irritating local builder – is not it. He may have a smile that can melt diamonds, but when he and Ophelia hit it off on the wrong foot, she starts to hate him with a passion.
Single-dad Brann isn’t all he seems. He’s built up a good business, though it doesn’t stop him from being lonely. Falling for a beautiful but stubborn heiress isn’t part of his master plan. But how can he not find Ophelia’s serene charm and whip-like comebacks irresistible?
As Brann and Ophelia work together, their arguments advance to attraction, and their desires ignite. But it’s more than Brann’s job’s worth to act on his feelings and Ophelia mustn’t, not if she’s to secure a wealthy match and stop her family from going under. A love this intense should be worth the fight, but constructing a happy ending is an almost impossible task without breaking all the rules.
